In class we demonstrated how the repeated squaring procedure can be used for computing the n-th power of a square matrix A" when n is a power of 2 using (log n) matrix multiplications. For example, if we want to compute A16 we use matrix multiplication 4 times as follows A2 = A. A, A+ = A2. A², A8 = A4 A4, and A16 = A8. A. Show how you can calculate A" when n is not a power of 2 using O(log n) matrix multiplications.
